Adobe Acrobat freezes for a lot of users

Dear Community,
since i think 2 month i have problem with the Adobe Acrobat. First i thought it was just me locally, but then also a lot of users on the Terminal Server told me that Adobe Acrobat is freezing for a few seconds.

Since then i tried all kind of settings, reading threads over threads just to find out that also a lot of other users and admins ar facing.

I have made a GPO just for Adobe Settings, at the moment i have tried following settings:

• Use Filename as Doc Title always
  HKCU\Software\Adobe\Adobe Acrobat\DC\AVGeneral\bAlwaysUseFileNameAsDocTitle = 1
• Maximal Entries for recently opened Documents at Homescreen
  HKCU\Software\Adobe\Adobe Acrobat\DC\AVGeneral\iMaxMRUCntToBeStored = 0
• Disable New Adobe UI
  HKCU\Software\Adobe\Adobe Acrobat\DC\AVGeneral\bEnableAV2 = 0
  
• Set Key, so its not the First Launch of Adobe Acrobat
  HKCU\Software\Adobe\Adobe Acrobat\DC\AVGeneral\bisFirstLaunch = 0
  
• Disable JavaScript
  HKCU\Software\Adobe\Acrobat Reader\DC\JSPrefs\bEnableJS = 0
  

What i have not set for all users yet, is the option to disable protected mode at startup. For me this option sounds really unsafe to enroll for all useres.
Could you give me some information what this settings mean, and if it is safe to set?

Or do you have any other solutions yet?

Current Version installed is 24.004.20272 
32bit on Windows Server 2019
Also installed Extended Asian Language font pack for Adobe Acrobat Reader in Version: 23.008.20421
Didn't find any Version 24 for this, think it was never released, am i right?

Really want to find a solution here in the next few weeks, otherwise i will use other PDF programs cause it really don't feel great if you get messages from users everyday how unstable they can work with your system.
